Histopathology of prepubertal rat testes subjected to various durations of spermatic cord torsion
spermatic cord torsion rat
2009/2/23
Sixty prepubertal rats were subjected to unilateral spermatic cord torsion for a duration of 0, 1, 3, 5, 9 or 12 hours. At the end of this period, the ipsilateral testes either were removed for imme...
Ultrastructure and intercellular vacuolization of isolated perfused and control rat testes
testis perfusion rat ultrastructure
2009/2/20
Isolated rat testes perfused in closed circuit with albuminated Krebs-Ringer bicarbonate buffer were examined by light and electron microscopic techniques in order to assess the structural integrity...
In Vitro Effect of Inhibin on Cyclic AMP-Phosphodiesterase Activity in Rat Testes
inhibin cyclic AMP-phosphodiesterase
2009/2/19
We have previously reported that incubation of testicular slices with inhibin in the presence of 6 x 10-8 M oFSH resulted in a dose-related reduction in accumulation of cyclic AMP due to a decreas...
Evaluation of the binding patterns of eleven FITC-conjugated lectins in Fischer 344 rat testes
eleven FITC-conjugated lectins Fischer 344 rat testes
2009/2/17
The binding patterns of 11 recently commercially available fluorescein isothiocyanate-conjugated lectins that have been uncharacterized or undercharacterized in rat testes and/or have an unknown or ...
2-Methoxyacetic acid（MAA）-induced spermatocyte apoptosis in human and rat testes：an in vitro comparison
2-Methoxyethanol human rat seminiferous tubules apoptosis calcium
2009/2/16
2-Methoxyethanol (2-ME) produces adverse reproductive effects in humans at an exposure level that is about 60-fold lower (2.6 mg/m3) than the concentration toxic to rat testes (167 mg/m3), suggest...
The immunohistochemical localization of alpha 2-macroglobulin in rat testes is consistent with its role in germ cell movement and spermiation
immunohistochemical localization alpha 2-macroglobulin rat testes
2009/2/13
alpha 2-Macroglobulin (alpha 2-MG) is a nonspecific protease inhibitor and binding protein for peptide hormones that was recently isolated from Sertoli cell-enriched culture medium and shown to be t...
Acute Adverse Effects of the Indenopyridine CDB-4022 on the Ultrastructure of Sertoli Cells, Spermatocytes, and Spermatids in Rat Testes：Comparison to the Known Sertoli Cell Toxicant Di-n-pentylphthalate（DPP）
Antifertility morphology ultrastructure seminiferous epithelium germ cells
2008/12/24
Acute effects of CDB-4022 on testicular ultrastructure were determined. Rats were treated orally with vehicle or a maximally effective single dose of CDB-4022 or Di-n-pentylphthalate (DPP). Prese...
Expression of the p63 and Notch Signaling Systems in Rat Testes During Postnatal Development：Comparison With Their Expression Levels in the Epididymis and Vas Deferens
Spermatogenesis p53 differentiation
2008/12/22
The role of tubular structures that contribute to the passage of spermatozoa is not solely passive; these structures actively contribute to their own functions, although these tubules and ducts ar...
